Question

Two ships were 700 miles apart at midnight and were headed directly towards each other if they collided at 10 a:m find the speeds of both ships if one was traveling 30 miles faster than the other

Answer 1

Given:

Two ships were 700 miles apart at midnight .

Let x be the speed of first ship and (x+30) be speed of second ship (faster ship).

The equation is,

`\begin{gathered} Dis\tan ce=rate* time \\ 10x+10(x+30)=700 \\ 10x+10x+300=700 \\ 20x=700-300 \\ 20x=400 \\ x=(400)/(20) \\ x=20 \end{gathered}`

Answer: the speed of first ship ( slower) is 20 miles and the speed of second ship ( faster) is 20+30=50 miles.
